ICP Furnace Control Board Kit for RGS210SDCA0AAAA — OEM | Ships Today

Overview

This OEM control board kit (part 1183618) is the integrated furnace control (IFC) that runs the ICP/Heil/Tempstar RGS210SDCA0AAAA gas furnace. It manages the entire heating sequence — inducer startup, pressure switch proving, ignition, gas valve timing, blower on/off delays, and safety lockouts — and monitors flame via the sensor circuit. Supplied as a kit, it typically includes the board plus mounting hardware and any required wiring adapters. A failed board causes no-heat conditions, erratic blower behavior, repeated lockouts, or diagnostic LED fault codes that don't clear after sensor and igniter checks.
